904 fluid capacity?

I use type f, and a quart of non detergent 30 wt.
I also jack up the car so the tires spin freely when first firing and adding fluid. Keeping it level dont forget.

I think mine took like 10 or 11 quarts.

I know some of the automatic cummins guys run HY-Gard john Deere fluid. Basically it takes heat better, but its part hydraulic oil. I dont know how it works in a car where its going to be shifting a lot.
